Some of the emulator features are presented in the <features> element in the domain XML although they are virtual CPUID feature bits when presented to the guest. To avoid confusing the users with these features, as they are not configurable via the <cpu> element, this patch adds an internal array where those can be stored privately instead of exposing them in the XML. Additionaly KVM feature bits are added as example usage of this code.
